Question 1 of 5

1. Question

Consider the following statements

Black soils are rich in Iron, magnesia and alumina.

Laterite soils are rich in lime, iron oxide and aluminium compounds.

Which of the above statements is/are correct?

a) 1 only

b) 2 only

c) Both

d) None

Correct

Solution: a)

Chemically, the black soils are rich in lime, iron, magnesia and alumina. They also contain potash. But they lack in phosphorous, nitrogen and organic matter.

Laterite soil – With rain, lime and silica are leached away, and soils rich in iron oxide and aluminium compound are left behind. These soils are poor in organic matter, nitrogen, phosphate and calcium,

while iron oxide and potash are in excess.

Question 2 of 5

2. Question

Consider the following statements:

The soil develops on crystalline igneous rocks in areas of low rainfall.

They are generally poor in nitrogen, phosphorous and humus.

They are fertile when fine-grained and are poor in fertility when they are coarse-grained.

The above statements refer to:

a) Laterite soil

b) Black Soil

c) Red and Yellow Soil

d) None of the above

Correct

Solution: c)

Red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern part of the Deccan Plateau. Along the piedmont zone of the Western Ghat, long stretch of area is occupied by red loamy soil. Yellow and red soils are also found in parts of Odisha and Chhattisgarh and in the southern parts of the middle Ganga plain. The soil develops a reddish colour due to a wide diffusion of iron in crystalline and metamorphic rocks. It looks yellow when it occurs in a hydrated form. The fine-grained red and yellow soils are normally fertile, whereas coarse-grained soils found in dry upland areas are poor in fertility. They are generally poor in nitrogen, phosphorous and humus.

5. Question

Which of the following are the characteristics of Submergent coastlines

Drowned river valleys

Wave cut platform

Presence offjords

Select the correct code:

a) 1, 2

b) 2, 3

c) 1, 3

d) 1, 2, 3

Correct

Solution: c)

Submergent Coasts are those that have been flooded by ocean waters because of a relative rise in the elevation of sea level at that location. The rise in sea level can be either the result of an increase in the volume of water in the ocean basins or the result of the land surface sinking, both of which create an apparent rise in the elevation of sea level. Features of a submergent coastline are drowned river valleys or rias and drowned glaciated valleys or fjords.

Estuaries are often the drowned mouths of rivers.

The Western Coastal Plains of the Indian subcontinent are examples of submergent coastline.

Emergent coasts are a result of local tectonic uplift of the land surface or a fall in the elevation of sea level because of a reduction in the water volume of ocean basins. Quite often, emergent coasts have rocky coastlines with cliffs and nearly flat platforms that extend inland where older coastal plains have been tectonically raised and are now elevated above the modern land and water interface.

The emergent coastline may have several specific landforms:

Raised beach

Wave cut platform

Sea cave
